sb/intel/ibexpeak: Remove 6/7 series chipset PCI IDs

Support for the Ibex Peak chipset was added in commit 888d559b03
("Support for Ibexpeak southbridge") by copy-pasting the bd82x6x
implementation and making appropriate changes. This resulted in some
of the PCI IDs for 6/7 series chipsets being left behind.

While some of these PCI IDs were removed in a commit b7d8788880
("ibexpeak/lpc: Fix PCIIDs."), there are still some that remain, we
remove those in this commit.
